    • The frequencies and the phases of frame timing signals are synchronized between a display apparatus and shutter glasses through a wireless network.The display apparatus counts a frame period and a period until the frame timing signal transitions next time after a beacon transmission timing using a TSF clock and transmits a synchronization packet in which these periods are described. On a shutter glasses side, when the synchronization packet has been received, the frequencies are synchronized on the basis of a difference between frame periods measured by both of them. In addition, phase control is performed on the basis of a difference between periods until next frame timing signals after a beacon is transmitted, which are measured by both of them.
    • 帧定时信号的频率和相位通过无线网络在显示装置和快门眼镜之间同步。 显示装置对帧周期和周期进行计数,直到帧定时信号在使用TSF时钟的信标发送定时之后转换到下一次,并发送描述了这些周期的同步分组。 在快门眼镜侧,当已经接收到同步分组时,基于由它们测量的帧周期之间的差异来同步频率。 此外,基于由它们两者测量的信标发送之后的下一帧定时信号之间的差异执行相位控制。

    • In an optical disk apparatus, transmittance and reflectance of a polarization beam splitter 13 to the S polarization and the P polarization of laser beams are adjusted so that a first polarization component level ratio in the laser beam received by a light receiver for reproducing signal 17 from a laser diode 11 via the polarization beam splitter 13, and a second polarization component level ratio in the laser beam received by a light receiver for monitoring light source 18 from the laser diode 11 via the polarization beam splitter 13 become equal or the difference between the first and the second polarization component level ratios becomes within a predetermined permissible range.
